I'm on the cusp of buying these - I'm mostly using these to play games/sim with the odd movie or show to watch.

BUT

I'm worried about the open design.I want an open design so that I can hear my better half trying to get my attention (especially as I plan on getting an oculus rift...). How loud is the sound leakage? Is it enough to annoy someone sitting 5-10 meters away at moderate volume?
